Square Enix producer Shinji Hashimoto was in the question-answering mood yesterday, responding to a handful of queries thrown his way via the Square Enix Partners Twitter account. After explaining to his curious followers that the company is "undecided" about downloadable ports of Seiken Densetsu 3 and mobile RPG Ever Heart Odyssey, Hashimoto addressed the possibility of DS remakes for Final Fantasy V and VI, stating (according to Andriasang's translation), "for FF5 and 6, there are technical issues as well, so at present these are also undecided."
We're not quite sure what that means. The only technical issue we can see in this situation is that Square Enix could put the original versions of both games on a single DS cart, and we would still pay $40 for it, making us technically insane.
